[Feature Request] Provide way to access a single feature

[JamesLMilner]

Is your feature request related to a problem? Please describe.
At the moment getting an arbitrary feature out of Terra Draw is quite difficult in that you have to get the whole snapshot, then filter through it to find the feature you're interested in. This could be quite costly if you have a lot of features in your store.

Describe your proposed idea for the solution to this problem
We offer a API for getting a copy of a single feature from the store

Describe alternatives you've considered
You can potentially use things like onChange and onFinish, but since getting a single feature is straight forward we should probably just offer it as an API

Additional context
No other context required I don't think!
